Specification of Letters Patent.

Patented Feb. 6, 191 2Q Application filed May 11, 1911.' Serial No. 626,459.

To all 'wh-om t may concern.

Be it .known that I, LEONARD P. Swovnn- LAND, a citizen of the United States, resid-- ing at Bourbon, in the county of Marshall and State of Indiana, have invented certain new and useful Improvements in Silos; and

I do hereby declare the followingz'to be a full, clear, and exact description vof the inventiom' such as will enable others skilled in the art to which it appertains to make andr use the same.

This invention relates to silos and :moreparticularly to doors, door-frames and the adjacent portion of a silo.

An object of the invention is to constructl a door and door-frame for a silo in such manner that the joints will be water and air tight.

Another object is to construct a door and door-frame for a silo in such manner that' the' door will be flush with the wall ofthe silo and will be securely held in position.

4Another object is to` provide novel means for holding fthe door or locking the same securely in position, and, a further object is tol provide a silo door and door-frame to receive said door and novel means for lockingithe door in position Within the frame, said locking means being of simple form and comprising a bar extending 4transversely across said door and held in such position by'tension grippers at both sides of the door and upon the door-frame. o

Other objects and advantages will be here'- inafter set forth and pointed out in the speciication and claim.

In the accompanying drawingswhich are made a part of this application, Figure 1 is a fragmentary View of a portion of a silo, showing my improved door, door-frame and door-lock. Fig. 2 is a detail view of one of the resilient lock bar grippers carried by the door. Fig. 3 isa similar view of the .resilient 'gripper carried by the frame to receive the free end of the lock bar, and,v

Fig. 4 is a section on line 4-4 of Fig. 1f,

' showing the water and air tight connection.

Referring to the drawings in which similar reference numerals .designate corresponding parts throughout the several views, 1 represents the timbers or boards of the silo, which 'are preferably connected by having their opposite edges beveled and grooved in the form of a V, in cross section, as shown at 2, and secured ,bythe rnetalllc splicing lplate 3, as shown in Fig. 4. l This i constitutes air and Water tightv joints which .are specially desirablel adjacent the door openings of silos.

The door-frame is formed :by means of the vertical strips 4 lsecured to the timbers 1, and'cross pieces 5, said cross pieces forming the top and bottom of said frame, while the timbers 1 formA the sides thereof. Securedto the strips 4 are the cross pieces 6, the greaterY portions of which rest upon thecross pieces 5 and a part of the depending portions of the cross pieces 6 project beyond the sides of the strips 5 to overlap the seams and also to form bearings for the top and bottom of the door to bear against when. in

position. A

The door is constructed of interlocking boards 7 braced by the bracing strips S'near opposite edges of the door, said bracing strips extending from the top to the bottom of the door. Upon the bracing strips 8 are secured the resilient locking bar gripping members 9, which are preferably formed by being bent upon themselves to present the bar receiving recess 10 andthe overlapping-` finger portion 11 and theopposite circulan ends 12, by means of which the gripping members are secured to the braces S. The locking bar 13 hasone end formed into a loop, as sho-wn at 14, to receive the pivot pin 15 secured in one of the door-frame side members 4. The bar 13 is then forced into the recesses 10 of the resilient grippin members 9 and under thengers 11 ofsai gripping bars. As the bar is swung in this 'position its free end engages against the inclined portion 16 of the resilient latch, 1 7 carried upon the'side bar 4 opposite the one to .which thebar is pivoted, and after said end of the bar 13 slides over this'inclined port-ion, it drops into the recess formed by the semic-ircularportion'lS of the gripping member "17 which is secured at its opposite ends 19 to the bar 4.

It will be understood that the free end of the rod 13 rests Within the semicircular pordrawing. the

4ing placed upon opposite sides of the door said door,

and the bar 13 extending transversely of the latter isdrawn tightly against the frame at both sides as well as the top and bottom. And as the gripping members are resilient, there is always a tendency to hold the door tightly closed;

From the foregoing it Will be readily seen that I have provided a door, door-frame and adjacent portions of a silo of improved construction with'positive air and Watery tight joints and connections. 1

What I claim is: In a silo, a door carrying resilient grip- -ping members, said door being Hush-with the wallof the silo, a locking bar carried by the door-frame of said silo, a resilient latch member carried by said door-frame opposite the point at which said bar is attached, said gripping members and said resilient -latch member being adapted to receive said locking bar to hold the door` in closed posisaid latch bur to said door-frame.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
